  • Page 67 Online4US User Manual Now we need to specify the message structure sent by the Online4US to the anybus. The Online4US is a node inside the anybus subnetwork. For each message sent by the Online4US we use a “transaction consume”. The transaction consume will contain all bytes that need to be decoded for a specific message.
